I got a backup bottleneck on VDP over NBD on a 1Gbps link. The backup is capped at 20MB/s very steadily, but if I start a cold VM migration between those two hosts (same source and destination) at the same time, it can still pump up to 110MB/s, i.e. definitely not CPU/IO/NETWORK bottlenecks. As I search through internet, someone suggested that there is a upper limit on the traffic at the management interface. I would like to know if I can lift the limitation, so that I can backup my single 3TB VM successfully within 24 hrs.
By the way, backup job will be forced to cancel after exactly 24 hrs? Anything can do about it?
